Application filed December 29, 1894. Serial No. 151.483. (No model.) Patented in England May 16,1884, No. 7,823; in France December 2, 1884, N0.1G5,7Q(i, and in Germany December-G, 1884, No. 31,846.

To all whom it nmy concern.-

Be 1t known that I, JAMES WoRRALL, of

Ordsall, Salford, in the county of Lancaster,

dyer, have invented certain new and useful Improvements in Machinery for Dressing Gut Pile Fabrics, ofwhich the followingis a specification.

The object of this invention is to simplify the construction of dressing machines fitted with reciprocating brushes that act transversely or from selvage to selvage of cut pile fabrics while the fabrics are being passed through the machine. In dressing fabrics of this class a large amount of fluff is disengaged from the fabric, and its accumulation about the bearings of the machine renders accidents by fire very frequent, the action of the working parts is interfered with, and a waste of power 111 driving the machine ensues. In order to avoid these defects, and to render the machinery more efficient, I impart a reciprocat ing motion to the brushes by means of frames in which they are fitted, such frames receiving a reciprocating motion from adjustable crankpins, or their equivalent, and thereby removing the necessity for placing rapidly-rotating axles below the cylinders which form the bed of the dressingunachine.

In Sheet I of the accompanying drawings Figure 1 is a plan View of a machine con structed according to my invention, but having omitted all of the brushes but one set, and alsohaving omitted the delivering and folding apparatus. In Sheet II Fig. 2 is an elevation of a part of the front end of the machine. In Sheet III Fig. 3 is a side view of the machine, showing also the overhead guide-rollcrs for t 'avcrsing the cloth back from the de livery end to the front end of the machine. Figs. at illustrate by a side view, a front view, and a plan the construction of the brushes in sections and the method of supporting the said sections. Fig. 5 is a transverse vertical section of one of the horizontal guides for the brush-frames.

In the figures, A A is a series of cylinders mounted in bearings in the rectangular framing B '3. Over these cylinders A the pile fabric to be dressed is passed, and by them the fabric is supported while under the brushing operation.

laterally, and it is then drawn down and C C is a series of brushes overlying the cylinders, and having their acting surfaces made concave to correspond with the cylinders over which they are placed.

0 O are a pair of reciprocating frames arranged longitudinally of the machine and carrying the brushes C. These frames are in tended to give to the brushes a to-and-fro motion transversely of the cut pile fabric as it is passed through the machine.

The frames slide in horizontal guides O, fitted to the ends of the main framing, and are actuated by pairs of rods D D, connected with crank -pins 7', carried by spurwheels E E, made fast to the ends of a pair of longitudinal shafts, E a, respectively. The said crankpins are adjustable in radial slots 0' in the spur-wheels (see Fi 2) for the purpose of varying the length of stroke of the rcciprocat- 7o ing movement imparted to the brush-frames and brushes by the said cranks. These shafts have their bearings in plumnier-bloc'ks fitted to the top of the main framing. and when driven by the means to be presently described they will impart to the brushes 0 the required traverse motion.

Below the cylinders A is a series of rollers, F, which serve to holdat tension the fabric that is led through the machine and impart a traveling motion thereto.

The fabric before it is brought under the operation of this machine has its pile cut by hand in the usual manner. It is next washed and scoured, and when dried is ready for the dressing machine. Being deposited in folds on the floor at the feeding-in end of the machine, it is led through series of fixed guide-bars, G, which straighten it out 0 passed under a pair of guide-rollers, g y, and thence up to and over the first cylinder A. In passing over this cylinder the face of the cloth is presented to a rotary brush, H, which, by its action, serves to raise the pile. 5 The fabric in passing round the top side of. the cylinder comes under the action of the first of the series of reciprocating brushes 0, the face of the fabric being presented to all the brushes of the series in turn. The fabric led down from the first cylinder passes under and over a group of guide'rollers, g g g, and

thence up to the second cylinder A. These guide-rollers serve to pass the fabric around a second rotary brush, H, which is situated directly under the space between the first and second cylinders, and to the action of which it is thus exposed at two pointsviz., at the point where it is leaving or has just left the first cylinder, and at the point just beyond where it passes on the second cylinder. The said brush is adjustable, as is also the brush H, for the purpose of maintaining an efficient brushing action. The fabric as it passes over the second cylinder is acted upon by the second series of reciprocating brushes, and from this cylinder it passes down and under a clothed guide-roller, F, to which rotary motion' is imparted for the purpose of drawing forward the fabric by friction of contact.

The drawings show a series of six cylinders mounted in the framing, each of which cylinders is divided at the middle of its length to make room for a central bearing.

The breadth ofthe machine is such as to allow of four breadths of fabric being brought under treatment simultaneously, and the guiding-rollers and brushes are made of a length to correspond to the length of the cylinders.

The fabric, as it passes up from the first driven roller F, is led up and over the third cylinder A, then down to a second roller F, and so on until it leaves thelast cylinder. It then passes underthe last driven guide-roller F, up over a drawing-roller, F, and down under a tension-roller, The fabric then passes upward to an overhead guide-roller, g, and away to an overhead drawing-roller, I, at the front of the machine. From this roller it passes to the folder K, pendent from the axle ofthe roller I, which folder lays it in folds upon a table, L, ready for removal.

By reference to the detached views, Fig. 4, Sheet III, the manner of constructing the reciprocating brushes and of fitting them to their frames "will be clearly understood. These brushes, it will be seen, do not present a continuous acting surface to the cloth, but they are formed of sections 0, spaced out and connected together by a pair'of parallel rods, 0. Upon these rods are strung any desired number of the sections 0, the brushes being fitted 'with lugs at their backs for the rods to pass through, and they are secured in position on the rods by means of clampingscrews fitted to the lugs. These sections 0 may be increased or diminished in number at pleasure, according ,to the nature of the work in hand, the brushing operation being lightened in proportion as the spaces between the sections'c are enlarged. These brushes are connected to their respective frames and made adjust able vertically therein by means of screwed driving and supporting pins 0', which pass down through the cross-bars of the framing and enter, tapped sockets in the back of certain sections of the brush, say three or four in each length of brush.

I will now explain the means for actuating main framing.

the various moving parts of the machine. M is the driving-shaft, mounted in bearings car ried by the main framing B, and fitted with band-pulleys and fiy-wheel. On theinner end of this shaft is a miter-wheel, m, which gears into a miter-wheel, m,on the longitudinal shaft E". The spur-wheel s E, keyed on the opposite ends of this shaft, gear into the spur-wheels E of the shaft E, and thereby transmit rotary motion thereto. From this shaft E the motion is taken for driving the rollers F and F,which conduct the fabric through the machine.

at is a miter-wheel, keyed on the shaft E and into it gears a miter-wheel, m on the horizontal shaft M, turning in bearings on the On the outer end of this shaft M is a belt-pulley. on", a belt from which serves to drive a belt-pulley, an, mounted on a shaft, m, turning in bearings 011 the main framing. A spur-pinion, m, on the boss of this pulley gears into a spur-wheel, m", on the axle of the drawing-roller F, and imparts rotarymotion thereto.- A spur-pinion, m, on the axle of this roller drives, through two intermediate pinions, n n, a pinion, m keyed on the axle of the last of the guide-rollers F, and so drives said roller. Keyed also to the axle of this roller is a miter-wheehm which gears with a miter-wheel, m, on one end of a longitudinal shaft, M, mounted in bracket-bearings standing out from the side of the main framing. From this shaft M having miterwheels at keyed thereon, and miter-wheels n on the shafts of the driven guide-rollers F, all the said rollers receive their motion.

The rotary brush H derives its motion through a belt, H", running on its pulley H from a pulley, H carried by the overhead shaft H, which also transmits motion by its pulley M* and a belt, M and pulleyM to the driving-shaft M. The rotary brush H is driven by pulleys h h and a belt, W, from the shaft of the rotary brush H. The roller I is driven by bands 1) p and pulleys 12 19 1) from the shaft M. On the axle of this roller I is a second pulley, i,which, through a band, i, and pulley K transmits rotary motion to a shaft, K, carried in bracket-bearings on the main framing. The opposite ends of this shaft K are fitted with cranks K, which serve to impart the requisite reciprocating motion to the folder K.

I have said that the pairs of spur-wheels E E are fitted with adjustable crank-pins, which are connected by rods D D to the frames 0'0 This is for the purpose of imparting a reciprocating motion to the brushes.

The brushes, constructed as already described, inlines of sections connected together by rods, are arranged in'and connected with their frames so that the first and every alternate line of brushes will be carried by one reciprocating frame-say O-and the others by the reciprocating frame 0 which frames slide in the longitudinal end guides, 0, carried by the main framing. By these means I cause the adjacent lines of brushes to move in opposite directions, so as to reverse their action on the cloth passing beneath them.

To prevent the escape of the lubricant applied to the guides O, I groove the lower face of said guides longitudinally, as shown at Fig. 5, Sheet III, and thus provide a receptacle for the lubricant.

Having now particularly described and as certained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is- 1. A brush for dressing-machines, consisting of separated brushsections and parallel rods, upon which the said brush-sections are adjustable at various distances apart, and means, substantially as herein described, for securing their adjustment, as and for the purpose herein set forth.

2. The combination of fabricsupporting cylinders, sliding brush-carrying frames and guides therefor, bruslrsections, and parallel rods which connect said sections together, and means, substantially as herein described, of connecting the brush-sections with said frame and adjusting them thereon relatively ,rods D 1), connecting said pins and frames,

and mechanism, substantially as described, for driving said shafts, all arranged substantiall y as herein set forth.
